T 0 all whom it may concern.'

Be it known that I, LORENZO Cozzo, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Door-Openers, of whichthe following is a specilication.

This invention relates to a device wherebydoors may be latched or heldin closed position and may be opened by merely pressing a button orplate. Vhile it is intended for general purposes, it is particularlyapplicable to cabinets.

The objects of this invention are to provide a simple and convenientmechanism for opening doors; to provide means whereby a door may beopened by pressing a button; to provide means for locking one or moredoors and having a pressure release device for unlocking the same andalso having a resilient means for openingthe doors;rand in general, toprovide such an improved construction as will be described moreffullyhereinafter.

In the accompanying drawings illustrating this invention:

Figure 1 is a front view of a cabinet with my improved door openerapplied thereto;

Fig. 2 is a sectional view taken on the line 2 2 of Fig. 1;

Fig. 3 is a sectional view taken on the line 3w3 of Fig. 2;

Fig. 4L is a sectional view taken on the line i-1 of Fig. 2; and,

Fig. 5 is a detail showing the door opening spring.

As shown in these drawings, 6 represents V a cabinet having doors 7 and8 which are hinged at 9 in the usual manner. The cabinet has a shelf orcross-piece 10 and a top 11. Each door is preferably provided with aspring 12 for opening the same. This spring may be secured to the shelf10 and its free end engages with a plate 13 on the door so that it willnot injure the same.

Each door is provided with a hook or catch 1st which is rigidly securedthereto in any well-known manner. These hooks engage with a latch bar 15which is mounted in a recess 16 in the cross-piece or partition 10. Thisbar is provided with lugs 17 which engage with springs 18 which raisethe bar over the bar 15 and engage with the bar to lock the doors inclosed position. When it is desired to open the doors, it is onlynecessary to press the button 21 which causes the bar 15 to move downout of engagement with the hooks 14. The springs 12 will then swing thedoors outwardly to open position. lt will be seen that, by means of thisarrangement, the cabinet may be constructed without any projecting latchmembers or knobs on the doors and will therefore, have a particularlyneat and attractive appearance. Furthermore, the doors may be operatedmuch more conveniently than by means of the ordinary latches. It will,of course, be noted that each door may be provided with a separatebutton and releasing device and it will also be noted that the devicemay be applied in various ways in order to produce the desired results.For

these reasons, do not wish to be limited to the exact constructionherein shown and described, except as specified in the following claim:

The combination with a cabinet having doors and springs tending to openthe doors, of a cross piece in the cabinet having a recess adjacent thefree edges of the doors, an inside hook on each door above the crosspiece, a beveled latch bar adapted to be seated in the recess inthecross piece, springs tending to raise the bar to engage the hooks,

a rod secured to the bar extending through a hole in the cabinet 'where'a recess is also provided, and a button secured to the rod and adaptedto be seated in the recess at the top of the cabinet where it isordinarily invisible but operable to depress the bar for releasing thebar and hooks, and allowing the doors to open.

Y LORENZO COZZO.
